The Brentwood-engineered AccuFAS submerged fixed-film system adds a fixed-growth surface for biomass to provide enhanced biological treatment and increase plant treatment capacity for municipal and industrial wastewater. Composed of Brentwood’s structured-sheet, fixed-film media, AccuFAS optimizes airflow and mixing while maximizing contact between the waste stream and biomass. Whether users are upgrading an existing plant, optimizing a new facility or adding nutrient removal to a lagoon, this technology is an ideal solution.
